The crawler crane is composed of a power unit, a working mechanism, a boom, a turntable, and a chassis.
1 boom
The truss structure is assembled for multiple sections, the length can be changed after adjusting the number of sections, the lower end is hinged to the front part of the turntable, and the top end is suspended and supported by the variable amplitude wire rope pulley set, which can change the inclination angle.
There is also a jib attached to the top of the boom, and the jib and the boom are at an angle. The hoisting mechanism has a main and auxiliary two-winding system, the main hoisting system is used for the jib hoisting, and the auxiliary hoisting system is used for the jib hoisting.
2 turntable
Mounted on the chassis by the slewing ring, the entire weight on the turret can be transmitted to the chassis, which is equipped with a power unit, a transmission system, a winch, a steering mechanism, a counterweight and a shed. The power unit can make the turntable 360° by the swing mechanism. The slewing ring consists of upper and lower rolling plates and rolling elements (balls, rollers) in between, which can transfer the whole weight on the turret to the chassis and ensure the free rotation of the turret.
3 chassis
The utility model comprises a running mechanism and a walking device: the former makes the crane walk forward and backward and turns left and right; the latter is composed of a crawler frame, a driving wheel, a guiding wheel, a supporting roller, a carrier roller and a crawler wheel. The power unit rotates the drive wheel through the vertical axis, the horizontal axis and the chain drive, thereby driving the guide wheel and the roller to make the whole machine roll along the track.
Low porosity clay bricks are made of ruby, mullite and combined clay as the main raw materials, molded under high pressure and sintered at high temperature. The product has excellent high temperature Physical properties and chemical corrosion resistance. Low porosity clay bricks have good stability, the degree of erosion does not occur sudden change, than ordinary clay bricks use cycle increased 2-3 times. Thermal conductivity, specific heat and solubility, respectively, than ordinary clay bricks 2 times higher than 10% and 40%, heat storage capacity than ordinary clay bricks higher than 50% -60%, can improve the thermal efficiency of the kiln.
